It is an object of my invention to improve a roundabout of this type andto this end I provide means for reversing the apparatus so thatthevmodels will start from below, will rise to the highest point andwill then be reversed and glide back. A

It is another object-of my invention to so effect the reversing` of themodel at the highest point that it is started for the glide, and to thisend resilient means arev connected with the reversing mechanism.

It is a further object of my invention to provide a collapsible girdercomprising two pivotally connected arms which in operativev positionconstitute a. nut for engaging the thread of the spindle, and, when notin pcration, can be folded te halt the length `of the complete girder.

v In the accompanying drawing an apparatus embodying myl invention isillustrated diagrammatically by `way of example.

- In the drawings, p

F ig. 1 is a perspective illustration ofthe' complete apparatus,

Fig. 2 is a similar view showing7 on a larger scale, the connection ofthe two girder arms,

Fig. 3 is a section along the axis of the spindle showing the reversingand gliding mechanism, 1 I

Fig. i is an elevation, andV l y Fig. 5 is a plan view of a girderf arm.

Referring to Fig. 1, 1 is the pedestal of the apparatus, 7 is a verticalSleeve on the pedestal, 34: is a supporting plate'at the -upper end ofthe sleeve on which the girderis resting in its yinitial position, S isa spindle secured in the sleeve 7, 9 is a wire wound about the spindleso as to constitute a thread, 3 and d are the pivotally connected armsof the girder, 5 is a model of an airplane which is suspended from thegirder 3 by means 212,997, and in Germany December 31, 1926.

which will presently be described, and 6 is a balance weight for theairplane model 5 which in the present instance has the form of anairship. It will be understood that I am not limited to a spindle thethread of which is constituted by a wire as shown and described,although this construction is preferred on account of its cheapness, noramI limited to any definite number of girders and models attachedthereto, and, instead of the balance weight 6 I might provide anotherairplane model. Y

A motor (not shown) .of some suitable kind, for instance of theclockwork type, is provided for imparting rotation to-thepropeller ofthel model 5L The girder comprises two arms 3, @L which may be ofchannel section, as shown. 10 is a bracket secured to the inner end ofthe arm 3, 10'l is a bracket secured to the corresponding end .et arm lthrough the medium of tongues 13, 14 and 11, 12, respectively, 15 is apivot connecting the brackets 10, 10 and 16 is a link with a hole'17,which is Apivoted in thel bracket 1() and is adapted to engagea pin onthe bracket 10. Both brackets are recessed for the spindle 8 at theirjoint and yprovided with tongues 19 and 20 constituting parts of afemale-thread engaging the thread of the spindle 8 so that the recesses,with the arms connect-ed by the link 16, will form acomplete nut for theY thread of the spindle 8,

Qlis a casing` secured to the other end of the spindleS which, as shownin Fig. 3, may be tubular for lightness., 23 is a spring surrounding thetube or spindle S, and 241 is a catch `connected with the spring andprojecting from a slot 22 in the wall oi the casing 21. j 27 is areversing shaft which is pivotally supported .inthe arm 3 on which themodel issuspended, tongues 25 and 26 constituting the bearings for theshaft. 31 is a lever projecting from the .innerend of the shaft 27 andadapted to engage the catch 28 if; a crown gear at the outer end of theshaft, 30 is a pinion meshing with the crown gear 28 and carried on abracket 29 at kthe arm '3, and 30 is a hook secured to the boss oi theoinien 3() and adapted'to support a link 32 kfrom which the model 5 issuspended. 33 is a hook at the eut-er end of y `the girder en which thebalance weight@ is suspended. d
